then, i can't create the libmicroros folder and the libmicroros.a, and it doesn't report any errors.

allen@ubuntu:~/Desktop/STM32F429ZIT6_uROS/microros_test/micro_ros_stm32cubemx_utils/microros_static_library$ ls
library_generation

we can see , only the library_generation folder in the microros_static_library but we lost the libmicroros folder and the libmicroros.a, why?

Start with micro_ros_stm32cubemx_utils/microros_static_library/library_generation/library_generation.sh and rerun the reported Docker command while capturing its complete output and exit status. Check where the script expects generated artifacts and compare that with the mounted project; done means the expected libmicroros folder and libmicroros.a are created or the failure is clearly reported.
